Catalytic subunit of the PI3K complex that mediates formation of phosphatidylinositol 3-phosphate; different complex forms are believed to play a role in multiple membrane trafficking pathways: PI3KC3-C1 is involved in initiation of autophagosomes and PI3KC3-C2 in maturation of autophagosomes and endocytosis.

PIK3C3
蛋白名
Phosphatidylinositol 3-kinase catalytic subunit type 3
亚基
Heterodimer. This subunit, part of a complex composed of regulatory and catalytic subunits, associates with regulatory subunit PIK3R4. Forms a complex with BECN1, PIK3R4 and either UVRAG and KIAA0226/Rubicon, or with ATG14. In this complex, presence of UVRAG and ATG14 are mutually exclusive. Part of a complex composed of PIK3R4 and PIK3CB (By similarity). Interacts with RAB7A in the presence of PIK3R4.
亚细胞定位
Midbody. Late endosome.
组织特异性
Ubiquitously expressed, with a highest expression in skeletal muscle.
相似性
Belongs to the PI3/PI4-kinase family. Contains 1 C2 PI3K-type domain. Contains 1 PI3K/PI4K domain. Contains 1 PIK helical domain.
功能
Catalytic subunit of the PI3K complex that mediates formation of phosphatidylinositol 3-phosphate which plays a key role in initiation and maturation of autophagosomes. Involved in the transport of lysosomal enzyme precursors to lysosomes. Required for the abcission step in cytokinesis. Required for transport from early to late endosomes.
